why don't writers have blogs?

You spend so much time writing, why would you want to have a blog? My suspicions were confirmed when I searched for blogs by some of my favorite writers: Stacey D'Erasmo, Philip Roth, Rupert Thomson, Mona Simpson, Dan Chaon... Nope! There's the other somewhat dubious issue of copyright protection. Maybe that's why the few fave writers with blogs I did find ended up writing about colonoscopies, summer retreats and dead relatives. Now that Margaret has invented the Long Pen remote book- signing device she might have a few extra minutes in the day to grace us with delicious morsels about her creative process. That's right, all you great writers out there... We don't want to know about your personal lives; we want to know about art!
